Related to common peroneal nerve: femoral nerve, tibial nerve

com·mon fib·u·lar nerve

[TA]
one of the terminal divisions of the sciatic nerve, diverging from the tibial nerve at the upper end of the popliteal fossa, then coursing with the biceps tendon along the lateral portion of the popliteal space to wind around the neck of the fibula, where it divides into the superficial and deep peroneal nerves. The common peroneal nerve, or its deep branch, is the most commonly injured nerve, being located in a lateral subcutaneous position at the fibular neck; a lesion causes a loss of ability to dorsiflex the foot ("foot drop").

common peroneal nerve

tibial nerve branch diverting from the main trunk in the popliteal fossa; it becomes superficial and winds around the neck of the fibula supplying lateral and anterior compartment muscles; susceptible to traumatic injury at neck of the fibula (e.g. motorcycle accident, or upper margin of a below-knee cast) with resultant weakness and wasting of subserved muscles leading to footdrop; it divides to form superficial and deep peroneal nerves

peroneal

pertaining to the fibula or to the outer side of the leg or shank; fibular.

common peroneal nerve
a nerve originating in the sciatic nerve; innervates parts of the calf and foot. See also Table 14.
peroneal muscles
see Table 13.4.
peroneal nerve block
achieved by injection of a local anesthetic into the groove between the tendons of long and lateral digital extensors on the hindlimb, usually in a horse. Anesthesia is obtained mainly over the craniolateral surface of the limb distal to this site and over the medial fetlock.
peroneal nerve paralysis
causes a characteristic inability to flex the hock and extend the digits so the animal bears weight on the dorsum of the foot. There is anesthesia of the cranial leg and dorsal paw or foot. Occurs in recumbent cattle and from trauma to the lateral stifle in dogs.

Muscles tested according to the nerves were: a) ulnar nerve (abductor digiti minimi), b) median nerve (abductor pollicis brevis), c) radial nerve (extensor carpi radialis and extensor carpi ulnaris), d) common peroneal nerve (tibialis anterior, peroneus longus and brevis) and e) posterior tibial nerve (small intrinsic muscles of feet).

Although bilateral peripheral nerve conduction parameters of the lower limbs were within our laboratory limits, distal motor latency of the right common peroneal nerve was relatively prolonged and compound muscle action potential amplitude was relatively lower compared to the left.
